Description

Technical Field

[0001] This utility model relates to the field of soil sample testing technology, specifically to a soil sample EC value testing device. Background Technology

[0002] The EC value (electrical conductivity) of soil samples is a key indicator for assessing soil salinity, solution ion concentration, and fertility status, and is widely used in agricultural production, soil environmental monitoring, and ecological restoration. An excessively high EC value indicates high soil salinity, which may cause salt damage to crops and affect seed germination and root water absorption. The EC value can indirectly reflect the total amount of nutrient ions in the soil. An excessively high EC value may indicate fertilizer damage or salt accumulation, while an excessively low EC value may indicate nutrient deficiency. In soilless cultivation in greenhouses and precision agriculture, the EC value is a core parameter for real-time control of nutrient solution concentration.

[0003] Chinese utility model patent CN216208758U discloses a multifunctional soil EC value detection device, including a functional detector, a secondary line, and a docking plate. Each secondary line has a connecting wire on one side, and each connecting wire has a docking groove fixedly connected to one side. Each docking plate has a docking block fixedly connected to one side. This utility model overcomes the shortcomings of existing technologies. By incorporating the docking plate, docking groove, and docking block, when replacing the functional detector, simply pulling the docking groove out of the docking block on the docking plate interrupts the circuit connection between the secondary and main lines. After removing the original functional detector and preparing the new one, the four connecting wires from the secondary line are inserted into the corresponding colored docking blocks using the docking grooves. The connection between the docking grooves and docking blocks establishes the circuit connection between the new functional detector, the control handle, and the main unit, eliminating the need for wiring tools.

[0004] However, during the use of this utility model, after testing the soil sample, the detection head needs to be cleaned frequently. When multiple soil samples need to be tested simultaneously, the detection efficiency of the soil samples will be greatly reduced, which cannot meet the needs of use. Therefore, a soil sample EC value detection device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a soil sample EC value detection device that offers the advantage of easy cleaning of the detection head. This solves the problem that existing detection devices require frequent cleaning of the detection head after soil sample testing, and that the detection efficiency is greatly reduced when multiple soil samples need to be tested simultaneously, thus failing to meet usage requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a soil sample EC value detection device, comprising a box and a top plate disposed on the top of the box, wherein a soil detector is disposed between the box and the top plate, and the interior of the box is provided with a cleaning positioning structure for facilitating cleaning of the soil detector;

[0007] The cleaning positioning structure includes a support plate that is slidably connected to its front side, a positioning cylinder that extends to its bottom and is internally threaded to the support plate, a cleaning head that is fixedly connected to the bottom end of the positioning cylinder, a threaded groove that is threaded to the support plate on the outer surface of the positioning cylinder, and a limit ring that is fixedly connected to the top end of the positioning cylinder.

[0008] Furthermore, the lower surface of the limiting ring abuts against the upper surface of the support plate, and the inner diameter of the cleaning head is equal to the outer diameter of the soil detector.

[0009] Furthermore, positioning blocks extending into the interior of the box are fixedly connected to both the left and right sides of the support plate, and positioning grooves that are adapted to the positioning blocks are provided on the inner wall of the box.

[0010] Furthermore, a storage rack extending to the front of the inner bottom wall of the box is slidably connected to the inner bottom wall of the box, and a sample container extending into the top of the storage rack is provided, and a protective pad for protecting the sample container is fixedly connected to the inner wall of the storage rack.

[0011] Furthermore, the number of sample containers is the same as the number of soil detectors, and a classification label is fixedly attached to the front of each sample container.

[0012] Furthermore, the left and right sides of the storage rack are fixedly connected with limiting strips extending into the interior of the box, and the inner wall of the box is provided with limiting grooves that are adapted to the limiting strips.

[0013] Furthermore, a support rod is fixedly connected between the housing and the top plate, a connecting plate is slidably connected to the outside of the support rod, and an electric push rod extending to the bottom is fixedly connected to the top of the top plate.

[0014] Furthermore, the output end of the electric push rod is fixedly connected to the connecting plate, and the soil detector is fixedly connected to the connecting plate.

[0015] Compared with the prior art, this utility model provides a soil sample EC value detection device, which has the following beneficial effects:

[0016] 1. This soil sample EC value detection device, by setting up a support plate and positioning cylinder, facilitates the positioning of the soil detector. Furthermore, by setting up a cleaning head, the detection head can be cleaned as it moves upward, making it easy to scrape off the soil residue adhering to its surface. The staff only needs to clean the cleaning head, reducing the possibility of over-cleaning the soil detector and ensuring its service life.

[0017] 2. This soil sample EC value detection device features a storage rack for positioning and storing sample containers, along with protective pads to safeguard them. Furthermore, the inclusion of categorized labels facilitates easy labeling of different soil samples, significantly improving soil testing efficiency. This addresses the problem of existing detection devices requiring frequent cleaning of the detection head after soil sample testing, which drastically reduces testing efficiency when testing multiple soil samples simultaneously, thus failing to meet usage requirements.
